Sentence examples for formation intervals from inspiring English sources

A series of mapping models which reflect the nonlinear relationships between seismic attributes and acoustic and density log data of various formation intervals in drilled well are constructed through neural network modeling.

A total of 65 sandstone samples have been taken from the cored Skagerrak Formation intervals of the 22/29-2 well (36) and the 22/29-3 well (29) for the reservoir quality analysis of this study (Tables 1, 2), and these have been selected entirely from sandstones ascribed to the fluvial channel facies (CF) (Tables 1, 2).

Formation interval density can be found from the interval velocities.
